{"id":"CVE-2026-64005","summary":"net/smc: Do not re-initialize smc hashtables","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: Do not re-initialize smc hashtables\n\nINIT_HLIST_HEAD(&smc_v*_hashinfo.ht) are called after smc_nl_init(),\nproto_register() and sock_register(). This can lead to smc_v*_hashinfo.ht\nbeing reset even though hash entries already exist and are being used,\npossibly resulting in a corrupted list.\n\nRemove unnecessary and dangerous re-initialisation of smc_v*_hashinfo.ht in\nsmc_init(); it is implicitly initialised to zero anyhow. Add\nHLIST_HEAD_INIT to the definitions for clarity.","modified":"2026-07-22T05:29:45.462652696Z","published":"2026-07-19T14:56:21.608Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64005.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0cc9d0ac22d02f1ba1884de5d6de9eaf8b45d82d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2006605006e5a4a11d93e1ebdbbe95764d24276f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/55cba6b883b41e5922c00ba9d4e3262131f46f1b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ec939367e700722ffbb1b7cacccbb1a3cf0ebd1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/64c96e497d5ada0b90e99bf58f893aa2b73dcfbc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e4389b0038781f19f97895186ed941ff8ac1678"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cdc79c05cc375f68ae87b0c74fdaac1a5c93155a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed7a758313011885347b854e97cb95903ef3c3f7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64005.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64005"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f16a7dd5cf27eeda187425c9c7d96802a549f9c4"},{"fixed":"cdc79c05cc375f68ae87b0c74fdaac1a5c93155a"},{"fixed":"2006605006e5a4a11d93e1ebdbbe95764d24276f"},{"fixed":"64c96e497d5ada0b90e99bf58f893aa2b73dcfbc"},{"fixed":"ed7a758313011885347b854e97cb95903ef3c3f7"},{"fixed":"0cc9d0ac22d02f1ba1884de5d6de9eaf8b45d82d"},{"fixed":"55cba6b883b41e5922c00ba9d4e3262131f46f1b"},{"fixed":"5ec939367e700722ffbb1b7cacccbb1a3cf0ebd1"},{"fixed":"9e4389b0038781f19f97895186ed941ff8ac1678"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64005.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.11.0"},{"fixed":"5.10.259"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.93"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.35"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64005.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
